are they CG approved? can you get in trouble if you run them without approval?? I know most of the blower guys run them.....but the only one thats cg approved is the small one...

Coast Guard approved air filters will say so on them.

So the nice big high flow K&N's are illegal???

Jeg's and Summit both offer a K&N that is C.G.-approved.

Mine said CC approved on the box but no where on the unit itself. I figured that would be a problem if inspected.

Yeah but its a little bitty one!

Yeah, I know. I'm looking around to find a C.G.-approved arrestor setup that will flow enough for my motors. I lose 50 horsepower just by putting on the flame arrestor that I have now.

I like the larger oval ones!!!

Took mine off my 540s... they didn't flow enough. And it was stamped USCG Approved on the metal top. Also on the rubber on the little filter. The larger ones aren't.
I switched to Eddie Marine 10X5 stainless arrestors

hell this one says mercury on it, what else can they say
